Description
Camshaft Types
Roller
LiftersThere
are
two
major
types
of
camshafts:
Flat
Tappet
and
Roller
Cams.
Lifters are not actually flat on the contact surface. They do have a slight curve, but it's hard to see. Roller Cams use a lifter with a roller on it. The roller cam looks like the flat tappet cam, but the cam lobes are very different. Roller cams have fatter lobes because of the way the cam lobe contacts the lifter. Roller lifters reduce friction, increase RPM potential and allow higher valve spring pressures to be used. Flat tappet camshafts can only withstand so much valve spring pressure pushing the lifter against the cam lobe.
Cam Lobe Profilesm as you increase valve spring pressure on a flat tappet cam, you increase wear on the cam lobe and the cam contact face of the lifter. This is a limiting factor when compared to a roller setup. To build big horsepower you need to have a cam with a lot of lift to open those valves wide. A lot of cam lift will require a higher pressure valve spring, giving the roller cam/lifter the advantage over flat tappet cams for building higher horsepower engines.
What are performance camshafts?
Camshafts
are
the
most
critical
part
of
your
engine's
performance.
Camshafts
use
a
combination
of
separation
angles,
lift,
duration
and
lobe
acceleration/ramp
rates
to
create
what
is
called
a
cam
profile
.
The
profile
you
choose
determines
where
your
maximum
horsepower
and
torque
will
occur.
What does duration of camshaft mean?
Camshaft duration is the period of time, measured in degrees of crankshaft rotation, that a valve is open. “Advertised duration” measures duration from the point where the cam manufacturer believes the lobe starts raising the lifter. This is called the checking height and it varies from manufacturer to manufacturer.
